your model breaks. becomes less accurate and doesnt use a constant..
your proving nothing

anyone can take any data and at one time manipulate it into appearing to conform to a straight line with a range of boundaries/buffer/outliers.
but if at a later date a peer takes your exact numbers and does it themselves and doesnt get the same results.. the theory is debunked

you endless showcasing that you have been working endlessly on it for 15 years shows its broke because you need to keep fixing it periodically

the top line doesnt, thanks for admitting it
however the blue (your supposed mid line) does not even follow the mid point of the market cycle
the green line doesnt even follow the bottom of the market

in short it has nothing to do with the market

you simply straightened a curve into a diagonal chart. and just drew a line for the axis not for the market data.
you then notice you cant get lines to fit the market data so then call it "undervalued" and "over priced" when the market data doesnt fit your silly theory

..
here is a thing though

you can look at the average hashrate of network over a period. look at current gen asics hashrate electric and hardware. and calculate the bitcoin price min and max dependant on dominant global countries electric price. and get a min/max mining cost.. and you will see the market has traded within that range

so not out of bounds of real economics

yep
2021 5k-75k was its global mining cost efficient/inefficient window and the market stayed inbounds
2022 10k-95k was its global mining cost efficient/inefficient window and the market stayed inbounds
2023 15k-110k was its global mining cost efficient/inefficient window and the market stayed inbounds

there are logical, social and economic reasons why the market stays inbounds of global min max mining
if no one on planet can mine for less no one wants to sell for less and everyone sees it cheaper to buy than mine so everyone is buying no one is selling causing a support line no one wants to cross
if everyone on planet can mine for less no one wants to buy for more and everyone sees it cheaper to mine to sell rather than buy, so everyone is mining/selling, no one is buying causing a resistance top line no one wants to cross

so when you then see the market hit those limits but not cross them you see the market is performing as expected when testing the boundaries
